ISSkin 使用技巧,WinXP 下的窗口阴影

原文 http://restools.hanzify.org/article.asp?id=109

是否觉得在使用 ISSkin 的时候感觉窗口太过平板,尤其对于那些窗口边缘和窗口内部颜色一致的皮肤尤其是这样,继续使用 Sakura 皮肤作为讲解,下图就是安装程序的截图,是否觉得就像一张纸一样,缺乏立体感呢?

作为 Vista 以上的 Windows 版本,我们都能够看见窗口的阴影,但是在 WinXP 里面却看不见,但是我们能看见的只有 Windows 提示的阴影.所以以下就是使用了 WinXP 的提示阴影效果,达至看上去窗口有一些立体的感觉.
